to the right of the center of the 1igure, the portion to the left of thecenter line of the figure being shown in sectional elevation, taken online 1 of Fig. 2 looking in the direction of the arrow; Fig. Q a centralsectional elevation of a port-ion of the car, taken on line 2 of Fig. `1looking in the direction of the arrow; Fig. a skeleton plan view, of theportion of the bottom framework shown in Fig. 2; and Fig. 4 a detailperspective view, showing the construction of the `side stakes and themanner of mounting them upon the transverse beams.

In constructing a car in accordance with my improvements, I provide acar frame formed of side trames a and end frames b, the end frames beingprovided with stakes o mounted on the outside thereof and secured to thetop plates of the end sills hereinafter described. These side stakes aremounted upon the inner sides of the side frames over the transversemembers of the bottom framework hereinafter described, .and are formedof tapered web portions d. The outer upright sides or edges of thestakes are. provided with vertical Hanges e and the inner edges withinclined iianges f, which extend from top to bottom of the stakes atright angles to the main web portions. The upper ends et the stakes areconnected by channels (31 having their fianges directed outwardly andthe lower ends of the stakes are simiiarl y connected by channels 18.The channels (31 and 18 are connected by diagonal members (50, which aresecured to their inner faces. Planks (352 are vsecured to the outerfaces of the stakes between said channels 61 and 1S. The diagonalmembers 60 are constructed of fiat plates, which lie against the innerfaces of the planks and are secured thereto as well as to the channels..The structure described forms a side truss capable of carryingtheweight from thecenter and end parts of the car to thebolsters and thetype of Ytruss is such that the diagonal members G0 are subjected totensile strainsonly, thereby rendering it possible to construct ;th'eniof fiat iintianged metal plates. The construction of the diagonalmembers of such tlat plates avoids restricting the interior width of thecar as would be done bythe use ot' tianged members, and Suchmembers willbe necessary it' the truss were of a form iniposing compressive strainsupon the diagonal. members. queen-post type and the diagonal members Thetruss is of the inverted slope downwardly away from the adjacent pointsof support, `tlralsis', the bolsters. By this means I am en 'bled tecarry the weight of the car upon ti. c si'de trusses without the use ofbulky trussesiwnioh would restrict. the interior dimensions of the car.structed according to my invention and provided with side trusses in theform above de scribed, the center sill serves merely to take the buiiingand draft strains and is supported from the bolsters, the load beingtransmitted to the bolsters by the side trusses and not by the centersill. A bottom trame is provided, having longitudinal center sills,

formed preferably of channel irons, and

each consisting of a cent-ral section y and end sections JL. The endsections of the eenter sills have vertical web portions 'i' of greaterthickness than the web portions j ot' the central sections.

Bod y bolstcrs are mounted over car trucks of any ordinary and wellknown type and havingr supporting,r wheels rihe body bolsters are eachformed of a pair otside plates Z which extend transversely from side toside of the car, beingl of greater depth at their central portions thanat their ends, as snown in Fig. l. A top plate fm, which forms thetension member, extends from end to end` of the bolster and laterallybeyond the outer faces of the side plates, being secured thereto bymeans of angles n, and a bottom plate 0 extends longitudinally of thebolster between the side plates near the lower edges thereof and issecured to the side plates by means of inner angle irons 2). A pluralityof vertical-transverse plates g are mounted near the longitudinal centerof each of the body holsters, and secured to the side members by meansof vertical angle irons r. These plates provide the necessary resistanceto the vertical thrusts or strains upon` the central hearings s. Upperlateral gusset plates r'. are secured to the opposite side plates bymeans of angle irons and bottom filler plates/v are mounted on oppositesides of the body bolsters over the laterally projecting' portions'ofbottom gusset plates wwhich extend laterally beyond the side plates atthe longitudinal central portion of the bolsterand are secured to thebottom flanges of the longitudinal center sills already described. Angleirons y have vertical lai'iged vportionsl, which extend inside of theside plates pt the bolster and are provided with horizontal. laterallyextending flange portions extending between the bottom gusset plateandthe lower edges ot' the side plates, as shown in Fig. 2. The centralsections of the longitudinalE center sills' are connected with the sideplates of the body Vholsters by means of vertical connecting angles 3,and the end sections of such sills are secured tothe opposite sidesofthe body llhen roobeneath the dumping doors.

holsters by means of similar vertical angle members 4. Transverse beamsare mounted upon the longitudinal sills at suitable intervals, formed ofvertical web portions 5, which are secured to the longitudinal sills bymeans of angle irons forming bottom flanges for such transverse beams.Top angle irons 7 and 8 form upper lateral flange portions ot' thetransverse beams, and the langle irons 8 are bent outwardly at theiropposite ends, forming a. space between them and vthe vertical webportions of the transverse beams, into which extend the depending webportions 9 of the side stakes, which are mounted upon the ends of suchtransverse beams. The vertical web portions of the side stakes andtransverse beams are secured together by means of suitable rivets,V`

as shown in Fig. 4. 4

Hinge plates 10 support the hinged sides of the doors. 4'These platesextend transversely over the center-sills from door to door and areprovided with bottomangles l1, by means of which their lower edges aresecured in position. The hinge plates'adjacent to the body holsters andend sills are secured to the top gusset plates which extend over thecenter sills, and those mounted near the transverse beams-or centrallyof the car-areseeured 'directly to the top flanges of the center sills,as sho-'svn in Fig. These hinge platos are provided with top flanges 12,and tbe central lloor plank 13 is laid thereon. Hinkle members 14 aremounted upon opposite sides of the vert-ical web por tions of suchplates at the opposite ends thereof, so as to form supports for thehinged members lvvhich are secured to the dumping bottom sections ordoors 16,v such hinge members being connected by means of pivot pins 17.

The dumping doors extend longitudinally on opposite sides or" the earbetween the transverse members of the carframe, and are adapted to swingupward to closed position so as to form bottom portions, as shown inFig. l, and downward to inelinedopen dumpingr positions. The inner edgesof the doors end beneath thefside edges of the center loor boards 13,and their out-er edges swing up into engagement with the bottom flangesof channel irons 18 which form the bottom-members ot` the side framesand are above the floor level. These channel irons are secured to thelewe/rends of the side stakes,` which, in turn, are secured to the bodyholsters by means of angle irons 19, as shown in Fig. 1. A
